My problem: I can't figure out how and where they mount! The standard ORDbot mounting positions don't work for these switches.

Most mechanical endstop designs use the holes that go through the body of the switch for mounting, but these look like I should be using the holes through the PCB which orient the switch 90 degrees away from what I'd consider normal operation of a mechanical end stop.

I'd love to use these switches (they have little LEDs that light up when they're activated - that's not only cool looking, but will help with calibration!).

It is hard to determine how large that is. Can you make a 3D model? Here is the first thing that comes to mind. I would use standard limit switches for X and X. They do not need to be calibrated and it is less wires for a std switch. For Z I might mount it on a block below the carriage and mount a screw in a block to the carriage for fine tuning.

@cozmicrayhah, sorry maybe I wasn't clear - since this appears to be a purpose built part for ORDbot, I was trying to see if there was a standard mounting for it because the pre-drilled holes and hardware in the reprap discount kit don't seem to suggest an existing way to mount these things.

I wanted to see if there are instructions before I go ahead and go through the effort of design/building a mount that might already exist!

But it looks like these things are new, so I'll have to come up with something. I like Bart's idea of using standard switches for X and Y for now (I've got loads) and concentrating on the Z.

I have never seen those before. I am sure a little hacking would make them fit. Ultimately I am not sure what they gain you other than the LED and a little less soldering. If they were a true drop in piece, that would be ideal.

Sacha, did you come up with a solution for the limit switches?I have just received my Hadron ORB from reprap discount and have the same problem.Cant seem to figure out how to use the switches that came with the kit?!

Hi Sacha, I second the above question - I received the same endstops from Reprapdiscount ... where did you end up mounting them? I was wondering if you could take some pictures. Another question is why 6 endstops were provided - as I understand it, you only really need 3 as the firmware can identify where the other end is?
